Stuttering prevalence, incidence and recovery rates depend on how we define it: Comment on Yairi & Ambrose' article Epidemiology of stuttering: 21st century advances

摘要

In the article, "Epidemiology of stuttering: 21st century advances", Yairi and Ambrose (Y&A) have reviewed research investigating incidence, prevalence and recovery from stuttering, and have concluded that the more recent research suggests that the lifetime incidence of stuttering may be substantially higher than the 5% figure that has frequently been cited in textbooks, and that the prevalence of stuttering in the population at large may be lower than the 1% figure frequently cited. This implies that a greater percentage of individuals may experience stuttering at some time in their lives than previously thought, and that recovery rates are greater than previously thought.
